Final answer:
The provided texts do not specify who the Continental Congress delegates toasted to at their final dinner, and without concrete historical sources, we cannot provide an accurate answer.
Step-by-step explanation:
The query about who the delegates of the Continental Congress toasted to during their final dinner is historically significant and relates to a profound moment of camaraderie and resolve among colonial leaders on the eve of American Independence. However, the provided texts do not explicitly state whom the Continental Congress delegates toasted to at their final dinner. Given the context of escalating tensions with Great Britain and the notable presence of figures such as George Washington, Patrick Henry, John Adams, Samuel Adams, John Dickinson, John Jay, John Hancock, Thomas Jefferson, and Benjamin Franklin, it could be surmised that toasts may have been made to the unity and fortitude of the colonies, or to figures emblematic of the struggle for independence. Nonetheless, without a specific source detailing the final dinner, any assertions would be speculative, and thus, in the interest of academic integrity, we can only acknowledge the question without providing an unsubstantiated answer.
